FTP logs show a 550 error message when you connect over a UNC share
This article was previously published under Q307788
When you use a server that is running Internet Information
Services (IIS), that has a virtual directory, and that connects remotely over a
Universal Naming Convention (UNC) share, you may receive a 550 error message in
the File Transfer Protocol (FTP) log, and the event log may show event ID 2009
with a source of
Srv. This behavior occurs most often when antivirus software is
running on the server.
The network server process provides remote procedure call
(RPC) support and file, print, and named pipe sharing. When IIS connects to a
remote server, it uses the server message block (SMB) protocol and connects to
the server service that is running on that computer. Another process that is
running on the computer may also have open file handles for the files that are
being transferred to the remote server. When the total number of open file
handles reaches 2048, the server process returns an error to the connecting IIS
FTP service.
This behavior is by design.

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.

didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
